Description

  The present invention relates to a simple shelter suitable for use as an evacuation protector in a disaster or a tent for one person.

  In the event of a natural disaster such as an earthquake or typhoon, relatively large public facilities such as public halls and gymnasiums are used as evacuation sites for residents in the area. At this time, the refugees are rarely assigned private rooms, and many neighboring residents are gathered in one large room, and they are forced to live together by living together such as so-called small fish sleeping. Is continued until the process proceeds to some extent.

  During this time, blankets, food, water, etc. are provided by the government, but the majority of evacuees only evacuate with only their personal belongings, excretion, change of clothes, toilet, bathing, In many cases, the privacy related to the individual life physiology remains untouched because the bedtime is shared with other people.

  Especially in the case of an earthquake disaster, you have to live this kind of life until the aftershock is completely settled, and if the house is damaged, the period of communal life is long and there is no privacy. Many people will stay awake again. For this reason, illness associated with the accumulation of stress occurs, and the morbidity rate such as a cold increases particularly in the cold season. Therefore, in order to prevent such an artificial secondary disaster due to crowding of people, it is conceivable to divide a large room into a plurality of parts by a simple partition or to introduce a tent for mountain sports in the room.

  However, when partitioning is implemented, the overall outlook is not good, and when an aftershock or the like occurs, if the partition falls, the evacuation route is obstructed, causing confusion.

  On the other hand, sports tents are self-supporting, easy to assemble, can be used in family units for 4 to 5 people, etc., and have the advantage of ensuring privacy such as changing clothes. In order to occupy the floor area accordingly, if there are individuals, if there are many refugees in the room, the surrounding area will be disturbed. In addition, although there is an advantage of being closed, the prospects from the inside to the outside or vice versa are not effective, and the response in case of drought due to aftershocks etc. is delayed.

  The present invention solves the above problems, is lightweight and portable, and can protect internal persons from external impacts. Evacuation protective equipment in disasters, tent for one person, etc. A preferred simple shelter is provided.

  In order to achieve the above-mentioned object, the simple shelter of the present invention is a cover formed by a lightweight high-strength material so that it can be expanded and contracted along the longitudinal direction. It is characterized in that it has a sufficient internal space and is portable in a contracted state.

  A second aspect of the present invention is a plurality of semicircular arc-shaped frames in which the cover is deployed at an appropriate interval along the longitudinal direction in the unfolded state, and a connection that spans between the frames and connects the frames. It is characterized by comprising a rod and a flexible heat insulating sheet joined to the inside of the frame and folded and expanded in accordance with expansion and contraction between the frames by the connecting rod.

  The invention of claim 3 is characterized in that the connecting rod can be bent at the center, and both ends of the connecting rod are pivotally joined to each frame so as to be folded and unfolded.

  The invention of claim 4 is characterized in that the connecting rod is detachably connected to each frame.

  The invention according to claim 5 is characterized in that the flexible heat-insulating sheet has a four-layer structure in which a nonwoven fabric layer is inside and a polyethylene layer and an aluminum vapor-deposited layer polyethylene layer are lined on the surface. The invention of claim 6 is characterized in that the lightweight high-strength material is a plurality of hard and semi-cylindrical outer shells arranged in an overlapping state.

  The invention of claim 7 is characterized in that the curtain is detachably attached to the front or rear opening of the shelter.

  The invention of claim 8 is characterized in that a longitudinal slit is formed in the center of the curtain.

  The invention of claim 9 is characterized in that the frame has a semi-arch shape and is detachably connected via a connecting means at the center in the width direction of the flexible heat insulating sheet.

  The invention according to claim 10 is characterized in that the cover body is a plurality of hard and semi-cylindrical outer shells arranged in a straight line at appropriate intervals, and a flexible heat insulating sheet connected at both ends between the outer shell bodies. It is characterized by comprising.

  The eleventh aspect of the present invention is such that a bar-passing portion formed in a bag shape along the longitudinal direction is integrated on both sides of the flexible heat-insulating sheet, and a support bar is inserted into the bar-passing portion. The outer shells are arranged in series.

  Therefore, in the invention according to claim 1, by expanding the shelter and entering the shelter, the body can be protected from falling objects and falling objects, and can be portable by contracting when not needed.

  Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. 1 to 5 show a first embodiment of the present invention.

  Among these, FIG. 1 has shown the use condition of the simple shelter of this invention. The simple shelter 1 is formed of a cover that can be expanded and contracted, and has a semi-cylindrical cross section. When the simple shelter 1 is expanded and installed on the floor or the ground, one adult feels cramped inside. It is configured to be able to form a space having an actual size so that the user can lie on his / her back.

  That is, the simple shelter 1 includes a plurality of semicircular arc-shaped frames 2 that are arranged at appropriate intervals along the axial direction of the cylindrical body that is the height direction, and each frame 2 at both installation ends. A connecting rod 3 for connecting each other in the height direction, a ground sheet 4 that is installed on the floor or the like and whose both side portions are connected to both ends of each frame 2, and a bag-like shape by sewing or the like on both upper sides of the ground sheet 4 And a back sheet 6 integrated with the rear part of the ground sheet 4 and the tent sheet 5 by sewing or the like and closing the rear opening. These sheets 4, 5 and 6 surround the entire body leaving a front opening.

  Further, fasteners 7 are arranged along the central longitudinal direction of the back sheet 6 and the left and right direction below the back sheet 6 so that the back sheet 6 can be opened to the left and right by operating the respective sliders 7a (see FIG. 1). See back view).

  In addition, although the front part side of the above simple shelter 1 is opened, this is because the inside of the simple shelter 1 does not breathe, the judgment of the external situation, and the situation of the person in the inside from the outside. Although it is intended to be able to be seen, when the outside air temperature is low, it can be kept warm by applying a tarp or a special curtain described later.

  Each frame 2 is made of a lightweight and high-strength material such as a fiber reinforced resin pole such as carbon or Kevlar, a metal pole such as duralumin or titanium, and the both ends of the frame 2 are locked to the ground sheet 4. The deformation of the both end portions in the radially outward direction is constrained to maintain a semicircular curved shape. Further, as shown in FIG. 2, the tent sheet 5 is stretched and locked to each frame 2 via a plurality of hanging elements 8.

  As shown in FIG. 2, a coupling block 9 for bearing this and coupling it to the coupling rod 3 is coupled to both side installed ends of each frame 2. As shown in an enlarged view of a part of FIG. 2, the end of the connecting rod 3 is pivotally pin-joined to the side of the connecting block 9 via a bracket 10. In addition, the connecting rod 3 is formed in a middle folding manner in which the central portion can be bent via a pin 11, whereby the simple shelter can be folded and unfolded in the longitudinal direction. In the state, the connecting rods 3 are held in a straight line, and the connecting rods 3 are folded from this state to enable shortening in the height direction. Although not shown, the connecting rod 3 is provided with a lock mechanism or the like for holding it in a straight state, so that the distance between the frames 2 is kept constant, and the tent sheet 5 is stretched in a tension state. be able to. In the illustrated example, the connecting rod 3 is provided at both ends of the frame 2, but it is more preferable to provide the connecting rod 3 also at the top of the simple shelter 1 that is the center of the frame 2. In the illustrated example, the connecting rod 3 is configured to bend upward, but may be bent inward toward the center of the arcuate frame 2.

  The ground sheet 4, the tent sheet 5 and the back sheet 6 are all made of the same material and have a cross section shown in FIG. In other words, it consists of a four-layer structure in which the nonwoven fabric layer a, polyethylene film layer b, aluminum vapor deposition layer c, and polyethylene film layer d are lined in order from the body facing part. It is a lightweight, high-strength thin sheet material that reflects far-infrared rays radiated from the body and can maintain a high temperature even when the outside air temperature is extremely low. In the case of the ground sheet 4, the arrangement is upside down from that shown in the figure. With these, the simple shelter 1 is directly installed on the floor surface or the ground, and even if a person lies on the inside, the decrease in body temperature is prevented. As a result, the internal space can be sufficiently warmed.

  Further, since the above materials are also high strength materials, for example, as shown in FIG. 1, when the simple shelter 1 is deployed, the sheets 4, 5, and 6 are stretched in tension, and a person is supine inside. If the frame falls within the elasticity and tension range of the frame 2 and the tent sheet 5 even if the object falls or falls due to an earthquake or the like, it will not break or break, Can protect.

  When the connecting rods 3 are folded from the unfolded state of the simple shelter 1, the simple shelter 1 is shortened in the height direction, and the ground sheet 5 and the tent sheet 6 are folded inward as shown in FIG. It is folded.

  Further, when the above simple shelter 1 is used as a container in a refuge or the like, as shown in FIG. 4 (b), if only half of each connecting rod 3 is folded, the space is reduced to half. Therefore, for example, when an evacuee leaves the evacuation center for a while, it is only necessary to store articles around him. If the tarp 12 is placed on the simple shelter 1, the front opening is closed and the interior is concealed. it can.

  The tarp 12 is made of a lightweight and high-strength heat insulating sheet shown in FIG. 3 and may be covered with a normal blanket, sheets, or the like as long as it is indoors. In addition, when it is desired to keep the neck from the simple shelter 1, the connecting rod 3 on the opening side may be folded, and the operation is simple.

  Furthermore, in order to facilitate transportability in the fully folded state shown in FIG. 4A, it can be accommodated and transported inside a carrying bag 20 having a semicircular arc shape as shown in FIG. 5, for example.

  A grip 21 is provided on both sides of the bag 20, and a fastener 22 that can be opened and closed by a slider 22 a is integrated along the center of the arc surface of the bag 20 so that the folded simple shelter 1 can be taken in and out.

  In the folded storage state, the frame 2 is stored along the inner side of the arc surface of the bag 20, and the inner side is only a folded flexible sheet material, and the bag 20 has a sufficient internal volume. In addition, a U-shaped fastener 23 that can be opened and closed by a slider 23a is provided, and the side is opened by opening this, and a flashlight, a transistor radio, a match, emergency food, and water are contained inside the bag 20. In addition to emergency supplies 24 such as plastic bottles, clothes, portable pillows, and folded tarp 12 can be put in and out, and it functions as an emergency carry bag in the event of a disaster. .

  In addition, it may be a backpack type instead of the handle 21, and in any case, by providing this bag 20 in a home, a car or the like, it can be taken out and used in the event of a disaster.

  In the present embodiment, each frame 2 is single, but it is subdivided into a plurality of addition types, and can be detached from each of the sheets 4, 5, 6 and the connecting block 9, and each is divided. In this case, the dedicated bag 20 is not particularly necessary.

  FIG. 6 shows a second embodiment of the present invention. In the figure, only members different from those in the first embodiment are denoted by different reference numerals, and the same members are denoted by the same reference numerals and description thereof is omitted.

  In the simple shelter 30 in the figure, the connecting rod 31 is detachably connected to the connecting block 32, and the connecting block 32 joined to both ends of the front and rear frames 2 has a rod receiver 32a having an L-shaped tube shape. In the coupling block 32 which is provided in an elbow shape and is joined to both ends of the intermediate frame 2, a rod receiver 32 a is provided in the shape of a cheese having a T-shape before and after that, and both sides of the ground sheet 4 are hanger 8 is the same as that of the first embodiment except that it is coupled to the middle of the connecting rod 32 via 8.

  In this embodiment, as described above, the frame 2 is subdivided into a plurality of addition types, and when the seats 4, 5, 6 and the connecting block 32 can be detached, the connecting rod is pulled out from the connecting block. 31 can also be disassembled, and is suitable for the case where each part is divided and stored in a bag or the like after being divided into parts and assembled at the site of use.

  In the first and second embodiments, the front portions of the simple shelters 1 and 30 are open, but may be closed in the same manner as the back seat 6 and opened and closed by the fastener 7. However, when closed in this way, the operability when escaped from the simple shelters 1 and 30 in the case of dredging is poor, and the ventilation is poor.

  However, when the simple shelters 1 and 30 are used indoors, it may be difficult to fall asleep because the lighting is too bright. Therefore, as shown in FIG. 7, a surface fastener 34 a is provided on the outer periphery of the shelter 30 near the opening edge of the tent sheet 5, while a surface fastener 34 b that meshes with the surface fastener 34 a is provided on the back surface of the curtain 35. In addition, by hanging the curtain 35 with the upper edge of the curtain 35 fixed to the opening edge of the tent sheet 5 through the double-sided fasteners 34a and 34b, the inside can be closed to a dark field state while ensuring air permeability. While the inside can be kept warm to some extent, in the case of a bag, it is possible to quickly escape from the shelter 30 while paying the curtain 35 by hand.

  In addition, although the case where it applied to the shelter 30 of 2nd Embodiment was demonstrated in the figure, the curtain 35 can be attached with the same method also in 1st Embodiment.

  Furthermore, in the first and second embodiments described above, the radius of the frame 2 is the same from the front to the rear. However, the rear side can be sequentially reduced according to the body shape.

  FIG. 8 shows a third embodiment of the present invention. In the figure, a simple shelter 40 includes a first outer shell body 41 having a semi-cylindrical shape, and a second outer shell body 42 closely slidably disposed inside the rear portion of the outer shell body 41. The space is sufficient for one person to lie in a state where both are continuous in the longitudinal direction.

  Both outer shells 41 and 42 are made of a molded body of a lightweight high-strength material such as GFRP (glass fiber reinforced resin) or CFRP (carbon fiber reinforced resin), and furniture collapses or rocks collide. It is now possible to completely protect people from the shock.

  In this state, the outer shells 41 and 42 are contracted to overlap each other, and the size is halved, and although it is somewhat bulky, it is made of a lightweight material, it can be carried.

  A pair of left and right handles 43 are provided on the inner surface near the opening of the first outer shell body 41, and an inside person stretches out and grasps the grip 43 as necessary. By pulling down 41 relatively, the external field of view and the like can be confirmed.

  This embodiment is particularly suitable for protecting the human body from impacts such as falling objects. Moreover, in this embodiment, when the outer shells 41 and 42 are connected to each other through appropriate connecting means and are turned upside down, they can be used as a transport stretcher for an injured person. In preparation for such a case, it is also possible to provide a connecting portion for the carrying rod or the like outside.

  FIG. 9 shows a fourth embodiment which is a further development of the third embodiment. The first outer shell body 41 covers the upper body with the handle 43 provided inside, and the center covers the abdomen to the thigh. The outer shell body 42 and the lower outer shell body 44 covering the toe portion are divided into three parts.

  Furthermore, curtains 46 and 47 are attached to the front opening portion of the first outer shell body 41 and the rear opening portion of the third outer shell body 44 via a hook-and-loop fastener 45, thereby providing windbreak and heat insulation functions. ing. In particular, the front curtain 46 is formed with a vertical slit 46a in the center as shown in the figure, and when looking at the surroundings, it is possible to look directly into the outside by opening the left and right bricks to the left and right. Yes.

  In this embodiment, the same effect as the third embodiment can be obtained, and the shelter 40 can be further divided into a plurality of parts as compared with the third embodiment, so that the portability can be improved. Can be carried in a carrying bag (see FIG. 5) as shown in the first embodiment, for example.

  Moreover, since the front side curtain 46 is a goodwill shape compared with the said 2nd Embodiment, the operativity in the case of looking at the exterior increases.

  10 to 13 show a fifth embodiment of the present invention. In the figure, this simple shelter 50 has a bag-like insertion portion 53 for inserting the left and right frames 52 inside the tent sheet 51 made of a flexible heat insulating sheet having a cross-sectional shape shown in FIG. The tent sheet 51 is three-dimensionally shaped like a bowl by alternately forming it by sewing or the like toward the center in the width direction and inserting the left and right frames 52 into the insertion portion 53.

  The left and right frames 52 have a semi-arched shape, and the outer ends thereof are fitted into the coupling block 32 of the connecting rod 31 as in the second embodiment, and as shown enlarged in a part of FIG. In the state assembled in a tent shape, the center side is connected to each other by winding a hook-and-loop fastener 54 as a connecting means so that the arch shape is maintained.

  In assembling the shelter 50, as shown in FIG. 12, first, the frame 52 on one side is inserted into the connecting rod 31, and then the frame 52 is inserted into the insertion portion 53 on one side of the tent sheet 51. If the frame 52 is also assembled to the tent sheet 51 in the same manner, and then the left and right frames 52 are connected to each other with the hook-and-loop fastener 54, a tent shape is formed as shown in FIG.

  The disassembling operation may be performed in the reverse procedure. In any case, since the frame 52 is divided into left and right parts, the labor for assembly and disassembly is minimized. Moreover, since it is subdivided also when carrying, the package can be reduced in size.

  It should be noted that in the present embodiment, the above shelter 50 can be deployed left and right with the hook-and-loop fastener 54 taken, and the area is almost doubled, as shown in FIG. Therefore, it can be used as a partition.

  In this case, since the force to round the arch is applied by the tension of the tent sheet 51, for example, a plurality of supporting tapes 55 provided with hook-and-loop fasteners 55a at both ends are coupled to both sides of the tent sheet 51 in the width direction of the outer surface. By setting it, it is possible to maintain independence in a standing state. Such use is suitable as a blindfold for work that requires privacy, such as windbreaks in nursing homes, breastfeeding, changing clothes, and changing diapers.

  In the present embodiment, the front and rear curtains are omitted, but it is needless to say that the curtain shown in FIG. 7 or FIG. 9 can be detachably arranged via a hook-and-loop fastener. In this embodiment, the hook-and-loop fastener 54 is wound as the connecting means between the frames 52. However, for example, a rigid coupling means such as a clamp can be used.

  14 and 15 show a sixth embodiment of the present invention. In the figure, this simple shelter 60 has three semi-cylindrical outer shells 61 made of lightweight, high-strength molded bodies arranged at appropriate intervals, and both sides of each outer shell 3 by sewing or the like. And a tent sheet 62 made of a flexible heat insulating sheet that is fixed and connected to the outer shells 61. As shown in FIGS. 14A and 15, a bar-passing portion 63 formed in a bag shape by sewing or the like is integrated on both sides of the tent sheet 62, and the support rod 64 is passed through the bar-passing portion 63. Thus, while maintaining the shape of the tent sheet 62 portion, the outer shells 61 are linearly arranged.

  What should be noted in the present embodiment is that the shelter 60 is turned upside down as shown in FIG. 15, and in this state, the support rod 64 is passed through the rod passage portion 63, whereby the support rod 64 protrudes forward and backward from the shelter 60. It can be used as a simple stretcher as a support part. In other words, in the event of an emergency disaster, injuries and the like occur, making it ideal for such use.

  Further, as shown in FIG. 14B, when the shelter 60 is not used, the outer shells 61 can be stored in a stacked state in which the tent sheets 62 are wound, so that compactness when not necessary can be achieved. .

  In the present embodiment, the front and rear curtains are omitted, but it is needless to say that the curtain shown in FIG. 7 or FIG. 9 can be detachably arranged via a hook-and-loop fastener.
